that type of such motors known as rotary` motors.

The objectsof my invention are to prov1de a. motor .of thev rotary type requiring and the stator; to eliminate all :cooling devices; and to produce a motor of highest efficiency at high temperatures.

I accomplish the above objects and other by meansof the construction ,illustrated in the accompanying drawings, which are "a part of this application for Letters Patent,

like characters of reference indicating like parts throughout the several views thereof, andv in which:

Figure l is a plan view of my device.' Fig. 2 is an enlarged sectional elevation 4 upon line 2 2 of Fig. 1.

F ig. 3 is an end elevation, parts being broken away.

Fig. 4 is a sectional elevation of the val ves,

A upon line l1 4 of Fig. 3.

Fi 5 is an elevation of the 'valve cam 35 whee.

Figs. .6, 7 and 8 are longitudinal sectionai elevations of the valve chambers illustrating the'three positions of the'valves.

Figs. 9, 10, 1j1, 12,13 and 1i are diagrammatical'sectional elevations to illustrate the cycle of operations.

Fig. 15 is a modified form of mounting the units.

In general my invention consistsl of a pair of. housings with a bladed rotor mounted upon a rotating shaft in each housing, and valve controlled passageways therebetween.

Suliicient liquid, preferably water, is contained in 'said housmgs and passageways to partially fill one of said housings, and the valves controlling said passageways are Voperated andtimed to permit the f low of liquid therethrough syncronpusly with tho cycle of operations now to be described.

In Fig. 9 the housing R is shown partially 'filled with liquid, l5 representing the rey 'he vali at ousing impressed by the ex andin as no mechanical packing between the rotor;A p g g desirable results to be`liei'einafter described blades 15 in housing 'the vproducts of combustion therein are 'volviug blades of the rotor, and the liquid is shown massed upon the sides of the housing or statorR -by centrifugal force created by the revolution of the blades 15.

The liquid is revolving with the blades, I

and since the total amounto liquid is less than vthe volume' of housing rR a central space 16 is created, intowhich has been in- ]ected an explosive insoluble gas.

The valve at A is set to open the passage- Way` between `the housings R and L, and

the gas is exlloded 'by an' elect-ric spark.

in space 16, evacnates housing R by wayof passageway and valve at A, and enters houstherethrough.

e liquid enters housing L upon a tanbeing closed, the liquid in '1go trance of "the liquid compresses said gas into a small space 17, as shown in Fig. 10.

The valve at A now moves to close its passageway into the housing L, and to open its passageway into housing R to the atmosphere, as shown in Fig. 10, thereby allowing the products of combustion to escape from the housing R, while the liquid in housing L. continues to rotate the rotor blades 15 therein by its momentum.

The rotor blades 15 in housing R continues in rotationafter the liquid has entirely evacuated said housing, and thereby caused to rotate with said blades, the centrifugal force thus produced helping to discharge said' products of combustion through the passageway and valve at A. v

The valve at A then movesjto close the passageway into each housing, as shown in. Fig. 11, wherein the valves at both A and B are shown closing their respect-ivev passageways completely.

A charge ofexplosive insoluble gas is now 1 injected into housing R. The valve at Bf is then moved to open the passageway respectivevthereto, and the compressed gas within the. space 17 in housing L is ex' ploded by electric spark, thus driving the 1 1.

quid intohousing R by Way ofpassageway and valve at B, as Shown in F 1g. 12.

j The liquid enters; housingjR tangentially at'the periphery thereof, and thereb is causedto rotate within housing R, w ich 'rotation is imparted to the rotor hades 15 in said housin When the lquid has entirely evacuated housing L, the valve at B moves to close .its passageway into housing R, and to open its passageway into housing 'L to the atmos.

phere, as shown infFig. 13.

The roducts ofcombustion .now are expolled ii'o' housin L throu'vh the passageway and valve at ,while the rotor blades l5 in housing R are rotated by the momentum of the liquid therein.

When the products of combustion have been expelled from housing L the valve at B closes its passageway entirely, and then a charge of explosive insoluble gas is injected into housin L, the rotor blades meantime being props led by the momentum oi the liquid in housing R, as shown in Fig. 14."

The valve at A then moves to the position shown in Fig. 9 and the cycle of operations is repeated.

It is `evident from the foregoing that the power transmission element in my device isthe liquid contained'therein; it isy also evident that this same liquid forms the packing between the rotor and the stator or housing; and it is further evident that since there are no close fitting moving parts exposed to the heat of the exploding gas, that no temperature limitation need be con-l densed, and wherefrom the condensed steam is returned as hoty liquid tothe housings.

The condensation of the steam produces a partial vacuum which greatly assists the evacuation; of the housings by the products of combustion, and the return of hot liquid enhances the efliciency of' the' device over any cold iii uid feed.

u lhecon ensei may be of any ordinary type knownto the art, and since it is no part of my invention, it is not illustrated in the drawings. s

'lhe housings .lt and L may be mounted side hy sido as indicated in Figs. Sl to 14 inclusi vc, und thc sha l'ts oi' the rotors geared together as hereinafter described, or the housings may hc axially alincd upon thc masses same'shaft and the passageways therebetween bent to suit, as illustrated in Fig. 15.

A preferred form of construction is illustrated in detail in the various figures of the drawings, which show the housings R and L formed of halves R, and'Rw and L, and

L2, said halves being flanged and connected by bolts, as shown in Fig.12.

.A hollow shaft 18 yis rotatably mounted inf Fixedly mounted upon each hollow shaftv 18, and respectively within housings R and L, is a spider consisting of a hub 22 and a series of radially disposed parallel pairs of arms 23, or the equivalent thereof, each of said pairs of arms having mounted thereon an impeller blade 15.

lhe' hub 22 and the hollow shaft 18 have registering orifices cut therein forming ports 24 communicating from the interior of said shaft to the interior of the respective houslng, as shownv in Fig. 2.

An intake valve 25 is mounted within one end of `hollow shaft 18, which end of said hollow shaft communicates with a fitting 26, which fittings are connected by a vman1- fold to a carbureter. The manifold and carbureter being old and well known devices in common use are not illustrated in the drawings, as they form no part of my invention.

lVithin saidhollow shaft 1' and opposite said intake valve 25 is mounts a low tension spark plug 27, as shown in Fig. 2. Said spark plug is lixedly mounted in a sleeve 28 which is longitudinally slidabiy and rotatably mounted Withinhollow -shaft 18, as shown in Fig. 2.

- Said sleeve 28 is secured to the`=hub of a` thimble 29 which thimble is screwed upon the end of hollow shaft 18, whereby the turning of said thimble 29 moves the sleeve 28 longitudinally within hollow shaft 18. The purpose of such movement is to effect the closing of ports 24 by the adjacent end kot sleeve 28 when the motor is shut down,

therebyexcluding moisture from the spark plugl 27. v

The thimble 29 is insulatingly bashed at 30, and the spark plug electric terminal 31 is'projected .beyond said thimble through said insulatip'g bushing to contact with. a spring conductor 32' which connects with a lundmg post 33, as shown. in Fig. 2, the spark plug beingV grounded in the machine in the usual manner.

Each of said housings R and L are provided with flanged ports 34 and 35, as shown in Fig. 3, the former constituting passage-A ways -B and the latter the pa'ssageways A that are shown in Figs. 9 to 14 inclusive. Mounted between the flanges of said ports are valve chambers 36, said valve chambers being connected integrally by a web 37 containing a bearing v38 for shaft 39, upon which shaft is secured gear 2l, as shown in Fig. 4.

The val-ves referred to as at A and at B in Figs. 9 to 14 inclusive are mounted within said valve chambers 36, and each valve consists of a cylindrical portion 37 with a transverse port 38 therethrough, and an apron portion 39, as shown in Figs. 6, 7 and 8. The valve port 38 is adapted to connect ports 34 and 35 respectively, as shown in Fig. 6, and also inFig. 3, where one valve chamber is sectioned; cylindrical portion 37 is adapted to close'each otl theportsl 34 and 35, as shown in Fig. T, and the apron portion 39 is adapted to close only one of the ports 34 or 35, leaving the other port' open into the valve chamber 36,- as shown in Fia. 8. y.

The. exhaust Jfrom the open port 34 or 35i as shown in Fig. 8, passes from valve cham- /ber 36 to the atmosphere, or to 'the condenser if one is used, through orifice 40.

A magneto and commutator'or timer ma be mounted directly upon one end oi sha 39, or geared or bolted thereto, as convenient,v for the purpose of generating electric current and distributing the same .to the spark plugs synchronously with the cycle of operations. Thesev devices being of ordinary construction and not a part of my invention are not illustrated in the. drawings. g-

T he valves in chamber 36 are operated by a cam Wheel 4l secured to Shaft l39 and co5, act-ing'with rollers 42 upon the valve stems 43,v as shown in Fig. 4. Said cam Wheel 4l is formed to operate the valves synchronously with the cycle of operations described in connection with Figs. 9 to 14 in clusive.

Mydevice is started by rotating shaft 39 from some outside source of power, as an electric starter or the like.

The power derived from taken from shaft 39 by pulleys or gears thereon, as most convenient.
